    Abstract:
    BACKGROUND: Overexpression of B-cell lymphoma 2 (bcl-2) protein is a simple biological adverse prognostic factor that could delimit the poor prognosis population candidate for improvement with high-dose therapy and autologous stem-cell transplantation (ASCT) in diffuse large B-cell lymphoma (DLBCL). Therefore, we conducted a risk-adapted phase II study with ASCT as consolidation therapy in low-intermediate risk (LIR) International Prognostic Index patients aged < or = 60 years with bcl-2 overexpression (bcl-2+). PATIENTS AND METHODS: Induction chemotherapy consisted of four courses of adriamycin, cyclophosphamide, vindesine, bleomycin, prednisone, once every 2 weeks. Responding bcl-2+ patients received ASCT as consolidation, and those without bcl-2 overexpression (bcl-2-) conventional chemotherapy. Three hundred and sixteen LIR patients with DLBCL, aged between 18 and 60 years, were included. Of these, 177 (56%) were bcl-2+ and 139 (44%) bcl-2-. RESULTS: Complete response rates after induction chemotherapy were similar in bcl-2+ and bcl-2- patients (74% versus 78%). Estimated 2-year event-free survival and disease-free survival for the bcl-2+ subgroup were 79% and 87%, for bcl-2- 84% and 92% and for the whole series 81% and 90%, respectively. CONCLUSIONS: These results demonstrate that taking into account biological characteristics in prospective multicenter trials allow successful adjustment of treatment and indicate that ASCT may counteract the adverse prognostic value of bcl-2 overexpression in responding LIR patients.
